Surface 2 Go - camera doesnt work, it breaks audio too #1589
Description
Hi. Its a followup of this NixOS/nixpkgs#435350
Long story short, im struggling to get camera to work on my Surface 2 Go. It should be supported according to this: https://github.com/linux-surface/linux-surface/wiki/Camera-Support
But regardless of the kernel used ( i have tried 6.12, 6.15 from this project, 6.16 from the repo and i believe 6.16 from the repo with surface patches), and the way i configure pipewire/wireplumber in hardware-configuration.nix, im getting segfaults of wireplumber, which are causing pipewire to crash and i am ending up with a tablet without a camera nor audio.

ELF object binary architecture: AMD x86-64
Here is my nix config with a history of things i have tried: https://github.com/Dinth/nixos-config/blob/main/hosts/michal-surface-go/hardware-configuration.nix
Currently im back on the default kernel, because it seems to work better with my surface, but happy to get back to 6.15 if thats gonna fix the camera and audio
What am i doing wrong?
